Pulse Duration:
Wider pulse duration settings will deliver stronger stimulation
for any given intensity setting. As mentioned in the Controls
section, by using a combination of intensity and pulse
duration, various pulse widths may stimulate different groups
of nerve fibers. The choice of which pulse duration to use is
partially dependent upon the Treatment Mode selected (refer
to the appropriate section).
Pulse Rate:
The Pulse Rate (hertz or pulses per second) chosen depends
greatly upon the type of electrode placement given to the
resident. When using contiguous and dermatome electrode
placements (i.e. stimulating directly through the area of pain
or localized enervation), a quick pulse rate (setting greater
than 80 Hz on the Pulse Rate Control) is typically desired. The
resident should not perceive individual pulses but rather have
the sensation of steady continuous stimulation. Despite any
general recommendations, individual residents may require
slight variations in the device settings, according to the nature
of their condition.
Treatment Mode:
Normal mode offers the practitioners complete control over
all the various treatment parameters of the instrument. Burst
Mode is analogous to the Low Rate TENS technique except
the low frequency individual pulses are replaced by individual
“bursts” of 7-10 individual pulses. It is thus a combination
of Conventional TENS and Low Rate TENS. In Burst Mode,
the treatment frequency is fixed by the instrument and is not
adjustable with the Frequency Rate control. Modulated Mode
attempts to prevent nerve accommodation by continuously
cycling the treatment intensity. When using Modulated
Mode increase the intensity only when the unit is at the
maximum intensity of the modulation cycle. If the intensity
